Just to point out (as a mobility scooter user) that it's not simply building accessibility that is an issue, but also the presence of drop-kerbs on sidewalks so you can get across roads; though cataloguing all of those would be a real headache, but I do spend a lot of time getting stuck when my usual route is closed for things like tree-felling, and the other side of the road is not accessible.
